This is a flying Rock-A-Chute Mark III rocket model built by G. Harry Stine, one of the American pioneers in the field of flying rocket and missile models, during the late 1950s. It is not known whether it was flown. The model has a pasteboard body, balsa nose and fins, and a plastic parachute. A solid propellant rocket motor propels the model, and then at the end of the vertical flight it forces the release of a parachute. The model is then retrieved and can be used again. The model is launched from a launch pad, with a hand-held launch controller being used to ignite the motor.
G. Harry Stine donated the model to the Smithsonian in 1973.
